Evented classes are classes which use an EventEmitter to call instance methods during runtime. To achieve this without this helper, you would instantiate an `EventEmitter` in the `__init__` method and then call `event_emitter.on` for every method on `self`. This decorator and the `on` function help make things look a little nicer by defining the event handler on the method in the class and then adding the `__init__` hook in a wrapper: ```py from pyee.cls import evented, on @evented class Evented: @on("event") def event_handler(self, *args, **kwargs): print(self, args, kwargs) evented_obj = Evented() evented_obj.event_emitter.emit( "event", "hello world", numbers=[1, 2, 3] ) ``` The `__init__` wrapper will create a `self.event_emitter: EventEmitter` automatically but you can also define your own event_emitter inside your class's unwrapped `__init__` method. For example, to use this decorator with a `TwistedEventEmitter`:: ```py @evented class Evented: def __init__(self): self.event_emitter = TwistedEventEmitter() @on("event") async def event_handler(self, *args, **kwargs): await self.some_async_action(*args, **kwargs) ``` r r0r1rNc|g|Ri|t|dst|_D]5}|j|jt ||j6dS)N event_emitter)hasattrr r8r-rr3r)r r0r1hhandlersog_inits rinitzevented..initis&t&&&v&&&t_-- 0!-D  B BA   ! !!'5qx+@+@ A A A A B Br)listrr)r!rr)r5r=r;r<s @@reventedr?7sZ#9ooH OO G 3<B3BsBcBdBBBBBBBCL JrN) dataclassesr functoolsrtypingrrrrr r pyeer r rrrr-r3r4r?rrrrDsm!!!!!!????????????????
